Product context

About King Series

King Series is designed for large factories, warehouses and high-heat industrial spaces. Its controlled air movement helps equalize temperatures and reduce stagnant air in large occupied spaces.

13,800 airflowFresh-air evaporative coolingIndustrial spaces

Operating principle

How it works

3 steps
01

Wet the pads

Water is circulated from the tank to saturate the evaporative cooling pads.

02

Draw in hot air

The fan or blower pulls hot outdoor air through the wet pads.

03

Deliver cooled air

Heat is absorbed through evaporation before filtered air reaches the occupied space.

Built for industrial use

Engineering features

High-volume fresh air

Continuous outdoor air movement helps reduce heat in open or semi-open facilities.

Efficient cooling pads

Even wetting supports stable evaporation, filtration and cooling performance.

Durable construction

Corrosion-resistant housing and reinforced components support long service life.

Simple controls

Timer, temperature and optional humidity controls make daily operation easier.

Before specifying

Operating notes

Cooling performance depends on entering air temperature, relative humidity and ventilation. The system performs best where cooled fresh air can move continuously through the space.

Service routine

Maintenance checklist

Before seasonal shutdownTurn off the water supply, empty and clean the tank, and dry the cooling pads.

During extended storageDrain circulating water and check the tank, pads and housing for scale, algae or corrosion.
